3 Claims.

This invention relates to improvements in lighting fixtures.

It is an object of this invention to increase the strength of the supports for canopies and globes without sacrificing the simplicity of the structure, but as a matter of fact making them easier to assemble, cheaper to manufacture, and easier to gain access to the globe when repairs are necessary.

The foregoing noted results are accomplished by limiting the number of parts to a minimum and without altering the outside appearance or design of the structure.

It is another object of this invention to provide a band for a canopy and globe comprising interlocking members which are relatively adjustable within limits when the lighting fixture is finally assembled.

Other and more specific improvements will become apparent as the description progresses.

In the drawings:

Fig. 1 is a view in side elevation of a lighting fixture embodying this invention.

Fig. 2 is a fragmentary sectional View taken on the line 2-2 of Fig. 1.

Fig. 3 is a fragmentary sectional view taken on the line 33 of Fig. 2.

Throughout the several views like parts are identified by the same reference characters.

The housing for an electric lamp herein disclosed comprises a glass canopy I and a glass globe 2. The globe 2 is supported on a base 3 which may be secured in any suitable manher to a pole (not shown). Secured to the flange 4 on the base, by means of screws 5, are a plurality of uprights 6 (preferably four in number and equi-distant from adjacent uprights). Each of the uprights comprise a pair of spaced legs I integrally connected with the base portion of the uprights, connected intermediate their ends at 8, and integrally connected at their upper ends with the clamping plate 9. The legs 1 preferably have a curvature approximately parallel ng the curvature of the globe 2.

The clamping plates 9 of the uprights are connected by means of band sections I0. These band sections are each provided at one end with a decorative portion I I integral therewith having a flange I2 on its rear face and also a lug I3 substantially the same height as the flange. The other end of each band section is provided with an offset portion I 4 integral therewith and receivable between the flange I2 and lug I3 in hooked relation to the decorative portion II of an adjacent band section I0.

Each clamping plate 9 on the upright 6 overlaps an offset portion I4 and lug I3 and is provided with a pair of vertically spaced bosses l5 positioned between the offset portion I4 and lug 23. The clamping plates 9 are secured to the decorative portions II by means of screws I6 which pass through the decorative portions II and into the bosses I5, thus clamping the band sections I0 together and to the uprights 6.

Resting on the top of the globe 2 is a flange ring II which is unsecured to the band sections or uprights. and is freely removable from the globe 2. The flange ring I! is provided with an inner flange Wall I3 projecting upwardly within the canopy I and an outer flange wall I9 projecting downwardly exteriorly of the globe 2. The canopy I is supported on the flange ring [1 and is secured against removal therefrom by means of clamping springs 20 held into resilient engagement with the canopy by bolts 2|. The bolts 2I are threaded through the decorative portions II and the clamping springs 20 are secured to the clamping plates 9 by means of screws 22. The clamping springs 20 comprise elongated plates each having the upper end hooked outwardly at 23 to serve as resilient means disposed between the bolt 2I and canopy I. The lower end of the clamping springs are provided with arcuately bent portions 24 resilently engaging the globe 2.

As is clearly illustrated in Fig. 2, the adjacent ends of the band sections may be longitudinally relatively adjusted to accommodate the structure to any inequalities in the diameter of the flange ring II. Thus the necessity of machining the parts to an exact size is eliminated and permitting the use of cast parts throughout. As will be observed, the band sections interlock with adjacent sections and even though the clamping plate 9 may becomeloose, the band sections will not disengage. Thus I have confined the number of parts to a minimum, made the parts easily adjustable and assembled, and interlocked the band sections so that they will not be separated if the parts become loosened.

If it is desired to gain access to the interior of the globe 2, it is only necessary to release the upper ends of the springs 20 by appropriately rotating the bolts 2| and then removing the canopy I by graspingthe finial 25 to raise the canopy from its position on the flange ring I1.

I claim:

1. In a support for a lamp housing, a base, a plurality of uprights carried by the base, and a plurality of band sections, each band section being detachably secured at one end to one of other of said ends being slidable relative to the adjacent band sections, whereby to alter the diameter of said band.

3. In a lighting fixture, a pair of band sections having complementary portions detachably 5 and slidably interlocked for permitting a limited peripheral adjustment of the band sections, and a band supporting upright detachably secured to one of said complementary portions and overlapping the other of said complementary portions 10 to hold said portions in interlocking relation.
